Foreword Iso (the International Organization for Standardization) is a worldwide federation of national standards institutes (ISO member bodies). The work of developing Inter- national Standards is carried out through ISo technical committees. Every member body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. International organizations,governmental and non-governmental, in liaison with Iso, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the Iso Council. International Standard ISO 3926 was developed by Technical Committee ISO/TC 8, Shipbuilding. This second edition was submitted directly to the Iso Council, in accordance with clause 5.10.1 of part 1 of the Directives for the technical work of ISo. It cancels and replaces the first edition (i.e. ISO 3926-1976), which had been approved by the member bodies of the following countries : Austria Ireland Romania Belgium Israel South Africa, Rep. of Brazil Italy Turkey Bulgaria Japan United Kingdom Czechoslovakia Netherlands USSR France Poland Yugoslavia The member body of the following country had expressed disapproval of the docu- ment on technical grounds : Germany,F.R.
